This document discusses IP CCTV transmission system design. It notes that the transmission system is an important component that sends and receives video signals between cameras, processing systems like DVRs and NVRs, and monitoring systems. Transmitting a strong, low-noise signal is vital for high quality images. Video transmission technologies include IP-based systems, which are gaining popularity as digital formats become more common. Selection factors for the best transmission strategy include distance between components, installation costs, existing infrastructure, and power availability.

1. INTRODUCTION
• The transmission system is an important component of the CCTV imaging chain that sends
and receives video signals between the cameras, the processing system (i.e., DVRs, NVRs,
and multiplexers) and the monitoring system (i.e. the display). Transmitting a strong video
signal with low noise is vital to producing a high-quality image on the monitor. Many
problems associated with the quality of a CCTV system signal are attributable to the
transmission system.
• Many types of video transmission technologies are available today. High-quality components
are needed to produce a high-quality result. The distance between a camera, monitor, and
storage system is one of the most important criteria for deciding which means of
transmission to use. IP-based systems are quickly gaining popularity as digital formats are
becoming more common within CCTV systems. Other selection factors include installation
costs, existing infrastructure, and availability of power. The options described below are
available when determining the best suited transmission strategy. Any copper conductor
(coaxial cable, twisted pair, etc.) exposed to an outdoor environment is susceptible to noise
and lightning strikes. Lightning protection is an essential added expense and could degrade
the video transmission if improperly installed and maintained.
